For those who know Calc: What is the quotient rule?

If I have the derivative of (f(x)/g(x)) does it equal (f'g-fg')/g' or (f'g-fg')/g^2??

    Easy way to remember the quotient rule: (lo-di-hi minus hi-di-lo)/ lo squared

    lo = denominator funct

    di hi = deriv. of numerator funct

    hi = simply the numerator funct

    di lo = deriv. of denom funct

    In other words:

    deriv of (f(x)/g(x)) = [(g' x f) - (f x g')] / [g^2]
